Hi David, I have passed the information on and am waiting for them to give it a try. I will send an update when I get the results. Thanks for your help!

Hi Scott, How long *should* bulk erase take on that chip? Did you or your contact at Ericson try increasing the timeout period? Try it out and let us know if that helps resolve the issue.

I am working on getting board names is there any other information you need?? From IBM: Found Micron/Numonyx/ST flash chip "N25Q128..3E" (16384 kB, SPI). This chip may contain one-time programmable memory. flashrom cannot read and may never be able to write it, hence it may not be able to completely clone the contents of this chip (see man page for details). Write/erase is not working yet on your programmer in its current configuration. Continuing anyway. Flash image seems to be a legacy BIOS. Disabling coreboot-related checks.
